But this time the outcomes aren’t so clear!

Review:Wow, this book is so amazingly great. I love it so much! The story is very original and has a fantastic, intriguing plot. It is so well-written, exciting, adventurous, and such a great read. I fell in love with the characters especially Yelena, Valek, Ari, and Janco who all have such strong qualities and are very likable. I couldn't put the book down once getting really into it, and I couldn't wait to see what would happen next. Poison Study always kept me hanging and made me never know what was going to happen...if Yelena would survive the many death threats and the attempts of murder or escape from her poison and being the food taster.

I felt so bad for all of torture and even rape she experienced with her old master and his son, and it was terrible that she was going to be hanged for just defending herself to stop the "experiments" from the master's son. You will not regret reading this fantastic book, so I definitely recommend it to everyone! Also, the cover is very pretty and fits with the story very well. The ending left off very nicely and now I can't wait to read two other books in the series and even her other series and standalone books. I really need to read Magic Study now, and I really hope Yelena and Valek are together in the end.
